Journal ArticleDOI
Experimental confirmation of the predicted shallow donor hydrogen state in zinc oxide.
Stephen J. Cox,Stephen J. Cox,E.A. Davis,Stephen P. Cottrell,P.J.C. King,James S. Lord,João Gil,H. V. Alberto,R. C. Vilão,J. Piroto Duarte,N. Ayres de Campos,A. Weidinger,R. L. Lichti,Stuart J. C. Irvine +13 more
TL;DR: It is confirmed that interstitial protium may act as a shallow donor in zinc oxide, by direct spectroscopic observation of its muonium counterpart, and results for the cadmium chalcogenides suggest that such shallow donor states are generic to the II-VI compounds.
Journal ArticleDOI
The NeXus data format
M Könnecke,Frederick Akeroyd,Herbert J. Bernstein,Aaron S. Brewster,Stuart I. Campbell,Bjørn Clausen,Stephen P. Cottrell,Jens Uwe Hoffmann,Pete R. Jemian,David Mannicke,Raymond Osborn,Peter F. Peterson,Tobias Richter,Jiro Suzuki,Benjamin Watts,E. Wintersberger,Joachim Wuttke +16 more
TL;DR: A description of the NeXus data format for X-ray and neutron scattering and muon spectroscopy is presented.
Journal ArticleDOI
Oxide muonics: II. Modelling the electrical activity of hydrogen in wide-gap and high-permittivity dielectrics
Stephen J. Cox,Stephen J. Cox,Jacob Gavartin,James S. Lord,Stephen P. Cottrell,João Gil,H. V. Alberto,J. Piroto Duarte,R. C. Vilão,N. Ayres de Campos,David J. Keeble,E.A. Davis,M. Charlton,D. P. van der Werf +13 more
TL;DR: In this article, a wide selection of binary oxides for this behaviour was screened using muonium as an accessible experimental model for hydrogen, and examples of the shallow-donor states that are required for n-type doping were inferred from hyperfine broadening or splitting of the muon spin rotation spectra.
Journal ArticleDOI
Shallow donor muonium states in II-VI semiconductor compounds
João Gil,H. V. Alberto,R. C. Vilão,J. Piroto Duarte,N. Ayres de Campos,A. Weidinger,J. Krauser,E.A. Davis,Stephen P. Cottrell,S. F. J. Cox,S. F. J. Cox +10 more
TL;DR: In this paper, experimental data on shallow donor muonium states in the tetrahedrally-bonded semiconductor compounds CdS, CdSe, cdTe, and ZnO are presented.
Journal ArticleDOI
Optimising a muon spectrometer for measurements at the ISIS pulsed muon source
Sean Giblin,Sean Giblin,Stephen P. Cottrell,P.J.C. King,S. Tomlinson,S. J. S. Jago,L. J. Randall,M. J. Roberts,J. Norris,S. Howarth,Q. B. Mutamba,Nigel J. Rhodes,F. A. Akeroyd +12 more
TL;DR: In this article, the authors describe the development of a state-of-the-art muon spectrometer for the ISIS pulsed muon source, which is a major upgrade of the highly successful EMU instrument, making effective use of the enhanced flux now available at the ISIS source.
